Petersons Deep Water Bottom Dredge

This 6" x 6" dredge is useful in all types of bottom substrates, except hard-packed clays. The two-way mechanism prevents accidental closure while in transit, yet triggers dredge with a spring-loaded release mechanism upon impact with the bottom, eliminating the need for a messenger. The top is covered with stainless steel screening to reduce frontal shock waves and prevent the escape of the sample upon retrieval. The effective sampling area is 36 square inches. Jaws, side plates, underlip plate, screen frame, and hinge pin are all made of #316 stainless steel. The top screen and fasteners are made from 18-8 stainless steel. Exterior weights and closing arms are constructed of powder-painted mild steel. A 3/8" nylon rope is recommended for raising and lowering dredge.
